Thread
Common sizes include M5, M6, M8, M10, M12, (1/4"-20, 5/16"-18, 3/8"-16) and larger.
The flange diameter is typically larger than the nut itself, providing a greater bearing surface.
Designed to provide a low profile while maintaining sufficient thread engagement for secure fastening.
Coarse Threads: Provide better resistance to cross-threading and are quicker to install and remove. Suitable for general applications.
Fine Threads: Offer greater resistance to loosening due to vibration and are used in precision applications where a tighter fit is required.
Materials
Steel: Often used for general applications. Available with different coatings such as zinc-plated, galvanized, or black oxide to enhance corrosion resistance.
Stainless Steel: Offers excellent resistance to rust and corrosion, making it suitable for outdoor and marine environments or where exposure to moisture and chemicals is common.
Brass: Used for its good corrosion resistance and electrical conductivity, ideal for electrical applications.
Nylon: Sometimes used in lightweight applications where electrical insulation or non-metallic properties are needed.
Applications:
Automotive: Widely used in vehicles for securing components that are subject to vibration, such as engine parts, exhaust systems, and body panels.
Industrial Machinery: Used in machines and equipment to secure components that experience movement or vibration.
Construction: Employed in fastening structural elements where strong, vibration-resistant connections are required.
Electrical and Electronics: Used to secure components in environments where vibration resistance is crucial, like in circuit boards and electrical panels.
Advantages
Vibration Resistance: The serrations on the flange provide excellent resistance to loosening due to vibrations, making these nuts ideal for dynamic applications.
Load Distribution: The integrated flange distributes the load over a larger area, reducing the risk of damage to the mating surface.
Integrated Washer: The built-in washer design simplifies installation and reduces the number of components needed.
